Letters Patent No. 104,814, dated June 28, 1870.

INIPROVEMENT IN REFRIGERATORS'FOR GONDENS ING- VAPORS FROM PERMENTING- VATS IN BREWERIES, 8cc.

The Schedule referred to in these Letters Patent and making part of the same.

I, LAWRENCE ANGSTER, of Newark, county of ltssex and State of New Jersey, have invented certain Improvements in Refrigerators for Condensing .arising from the same will be permitted to escape, and

not return in condensed form to the fermenting vat, while the lupnlin, or flavoring-property of the hops, shall be retained in the fermenting beer, which result I accomplish by placing immediately over the tuns or vat-s containing the fermenting .beer an ice-chamber, against which the gases impinge, and being thereby condensed are prevented to return to the vats. by means of a double gutter, which receive both the condensed vapors arising from the vat and the melted ice, and carries them outside of the refrigerator, while a constant supply of fresh air is admitted to the. fermentation-chamber, as I will further explain by reference to the drawing, in which Figurelrepresents a sectional elevation of my brewers refrigerator, showing the beer-vault, fermentation chamber, ice-chamber, and double gutter, for preventing return of the gases to the vat;

Figure 2 is a View showing the under 'side ofthe icechambcr, which is employed as a condenser to the vat, and also the double gutters, which preventreturn of the condensed gases to the rat,

Figure 3, a view of inside of roof. of condensing chamber; and

Figure 4, a top View of the ice-floor.

In the said drawing- A A indicates the double walls of the refrigerator, the intervening space B being filled with charcoal, shavings, or other non-conductor of heat, and

O is the' roof.

E is the ice-chamber, containing a rack, F, on which the ice is placed, said rack being surmounted by a condenser, G, for condensing the vapor arising from the ice, and conducting the same into the gutters H H, from which the melted ice is conducted by pipes outside the refrigerator.

K is the floor of the ice-chamber, (see fig. 4 which has a metallic surface, L. The under side or ceiling of this floor is provided with inverted hollow pyramids M, against which the volatile gases arising from the ferment-ing beer (placed in vats N in the chamber N) impinges, and, being condensed, drop into a series of gutters, O, which run below the -pyramids, and thence conducted by pipes P outside the refrigerator.

R is an auxiliary gutter, or-casing to the gutter 0, for the purpose of preventing return of the gases condensed on the colder gutter O, by dropping into the fermenting vat. v

S are ventilators, for supplying the vat-chamber with fresh air, and r 'I is a vault containing barrels, into which the beer, after fermentation, is run.

I am aware that a patent had been granted to me, November 30, 1869, for an improved refrigerator for condensing vapors from fermenting vats in breweries, which, in the absence of the metallic floor L and secondary 'gutters R, I found was partially inoperative, inasmuch as thevolatile gases, after striking the cold gutters O and being condensed thereby, dropped back into the fermenting vat, this defect being overcome by the warmer auxiliary gutter It, receiving the dripping from the colder gutter O, and conducting the condensed gases and melted ice outside the refrigerator; and also the open floor, which permitted access of the volatile gases to the ice, is' in like-manner remedied by the metallic floor, which aids in keeping the ice intact, condenses the gases, returning them by the. inverted pyramids to the gutters 0 That I claim is- The auxiliary gutter R, metallic floor L, and inverted hollow pyramids M, when used in combination with the ice-chamber'E G H, gutters O, and fermenting vat N, substantially as and for the purposes described and set forth.

In testimony whereof I have hereunto set my signature this 2d day of May, 187 0.
